The icons in Mac OS X Mail's toolbar are pretty self-explanatory, but the text is still turned on by default. Fortunately, it's easy to change that and save some screen real estate, too.
Set the Mac OS X Mail Toolbar to Show Icons Only
To make the Mac OS X Mail toolbar show icons only:
- Click anywhere on the Mac OS X Mail toolbar while holding down the Ctrl key.
- Select Icon Only from the menu.
